我试了一下，用jdk1.4，在apache tomcat5.0.28下启动时filter报错，但是只有一句话

error filterstart

我们现在开发时的环境要求eclipse+tomcat5.0.28，只是最后发布到was5.1下。我在was5.1下试了一下，程序在was下filter是可以正确运行的，所以想请fins修改一下filter，你的这个filter在tomcat5.0.28+jdk1.4下运行不起来
另外，我用tomcat5.5.12试过，程序也可以正确运行，只有tomcat5.0.28不行

不应该啊
因为我们的开发环境就是 5.0.28 :'(

你的web.xml是怎么写的 发来看看呗 谢谢

我的架构以前已经告诉过您了，是struts1.1+spring1.2.9+hibernate3.2.3，然后我用了ecside1.3呈现列表页面，我的web.xml如下：

这个文件在jdk1.4.2_01+tomcat5.0.28的环境下运行不起来
我google了一下，网上有些文章是认为tomcat5.0.28的filter功能有问题，但是我们目前开发必须用jdk1.4
